Not a fan of talk radio of any political stripe generally, but I gotta think that WMAL-FM is on the horizon. DC has to be the worst market for AM in the northeast. Most viable formats appear to be covered in the area. 105.9 was the second classic rock station. News, sports, 3 varieties of AC, alternative, country, R&B, hip-hop, gospel, and CHR all exist on FM. At best, another music format might be a CHR, but like Journey, that would eat into 107.3.
Additionally, the area is covered in a patchwork fashion by some fairly popular rimshot Hot AC and country stations from Frederick, Fredericksburg, Winchester, etc.
You oughta know? Really, no, you oughta know!
